Biomechanical in vitro laboratory study. ⋯ Constrained dual-screw fixation characteristics in modern AISF implants can improve resistance to cyclic loading and pullout forces. DC constructs bear the potential to reduce the mechanical shortcomings of AISF.

Case report. ⋯ The remaining mobility at the nonossified lesion, where the point of the beak-type OPLL compressed the spinal cord, might have caused the myelopathy in this patient. We propose that stabilization with PSI stimulates bone remodeling of nonossified lesions, leading to a reduction of OPLL. This finding provides a clue about the mechanisms responsible for neurological improvement after PSI for T-OPLL.
